A new study out of the University of Exeter says catching a whiff of noxious gasses, like those in flatulence, could help the human body repair cell damage and prevent debilitating diseases such as cancer.

“Although hydrogen sulfide gas”—produced when bacteria breaks down food—”is well known as a pungent, foul-smelling gas in rotten eggs and flatulence, it is naturally produced in the body and could in fact be a healthcare hero with significant implications for future therapies for a variety of diseases,” Dr. Mark Wood said in a university release.

Although the stinky gas can be noxious in large doses, scientists believe that a whiff here and there has the power to reduce risks of cancer, strokes, heart attacks, arthritis, and dementia by preserving mitochondria.

A couple of years ago a seemingly identical study found that inhaling the farts from other people can weaken your immune system. (I never found out if that means inhaling your own farts has a different effect.)

Now this study says it can repair your cells and help against diseases?

Which is it, researchers?! Should I go around sniffing other people's farts or shouldn't I?!
